How much power does a Level 2 Cam kit add?
The final numbers were 470 hp at 4,800 and 484 lb-ft at 6,100 rpm. Timing was 25 degrees total, and the air/fuel ratio was 11.3:1. CPR ran the engine to 6,600 rpm, but it didn't make any power past 6,200 with the stock cam. The Level 2 cam kit comes with dual-valve springs with seals, retainers, keepers, and gaskets.
What Cam do I need for my LS3?
If you need a 50-states legal cam for your LS3, use part number 146-103-11. The 8710 cam has 230 degrees of intake duration and 242 degrees of exhaust duration at 0.050 tappet lift.
What are the specs of a sum Summit Stage 3 cam?
Summit Stage 3 Cam Specs: 230/242 duration, 0.625/0.605 lift, 113 lobe separation angle, 1.7:1 rocker arm ratio Double Platinum LS Dual Valve Spring and Retainer Kit (PN TFS-2500286P)
Will a sum-8710 Cam fit a Chevy LS3?
They gave us the SUM-8710. It fits any 2008—2017 Camaro or Corvette 6.2L LS3 that does not have variable valve timing (VVT) or active fuel management (AFM) and only requires a new three-bolt sprocket and performance valve springs to run. If you need a 50-states legal cam for your LS3, use part number 146-103-11.
How wide is a cam sprocket?
Each tooth in the cam sprocket is about 7.5 degrees wide; aligning the dots is only accurate to 7.5 degrees. The installed centerline could be 107 or 123, which is one tooth off in each direction. Therefore, if you want to install the cam at 112 or 118, you can’t get there with the lining-up-the-dots method. However, actually doing the lining-up-the-dots as the first step saves you a lot of time in the long run. It also catches a one-tooth-off error.
What is the camshaft in an engine?
The camshaft is part of the engine’s short block, so cranks, pistons, rods, and valvetrain need to be considered. On the other hand, cylinder heads are very popular.
What is the purpose of a camshaft?
The main function of the camshaft is to open the valves. The tappet is the first part that helps transfer the cam movement toward the valves; the pushrods are the next part in the valvetrain. This chapter covers the cam and tappets; the pushrods are covered with the rest of the valvetrain in Chapter 7. Common.
Why does the camshaft run at half crank speed?
Because the cycle takes two revolutions, the camshaft runs at half-crank speed and the cam sprocket is twice as large as the crank sprocket. Match the cam’s lift and duration to combustion chamber capacity, head port size, exhaust system design, and other aspects of the engine.
How big is a tappet?
A tappet is about 1 inch in diameter and 2 to 3 inches long. The face of the tappet rides directly on the lobe of the cam. Therefore, the tappets must be the same as the cam design, that is, hydraulic to hydraulic, mechanical to mechanical, etc.
What is cam lift?
These two types of lift are influenced by the rocker arm ratio (typically 1.5 or 1.6). Valve lift tends to be the most popular lift number, and it is also the easiest to measure directly.
How are A engine and magnum cams similar?
A-engine and Magnum cams look similar because the difference in overall length is only about 1/4 inch. The distributor drive gear is located at the rear of the cam along with a small number-5 bearing journal. The other four journals are basically the same size (just under 2 inches). Cams are made of cast iron or steel.
